To all whom, it may concern.-

Be it known that 1, JosrrUA JO N NIX, acitizen of the United States, anda resident of Los Angeles, in the county of Los Angeles and State ofCalifornia, have invented a new and Improved Gas-Generator, of which thefollowing is a clear, full, and exact description.

. The invention relates to an apparatus for generating gas, particularlyfrom hydrocarbon, oil atomized by air and steam.

An important feature of the invention lies in the provision of twocombustion and expansion chambers separated by a shallow checkerwork oflarge area, thus allowing perfect expansion of the gas and a consequentgain in volume and bringing about a thorough association between the gasand checker-work, so as eventually to [ix the gas.

The invention involves various other features, all of which will befully set forth hereinafter and pointed out in the claims.

Reference is bad to the accompanying drawings, which illustrate thepreferred embodiment of my invention, in which drawings like charactersof reference indicate like parts in the views, and in which- Figure 1 isa vertical longitudinal section of the invention. Fig. 2 is across-section on the line 2 2 of Fig. 1, and Fig. 3 is a detail View ofthe oil-spraying pipe.

10 indicates the tire-brick walls of the apparatus, which preferably arecovered with metallic sheathing 11. 10 indicates manholes in said walls,and 11 the covers therefor. These walls are preferably of thecross-sectional form shown in Fig. 2, this being considered to be thebest adapted to the purpose. Constructed within the lower part of thechamber 10 are ascries of piers 12, on which is erected a checker-work14. This checker-work is relatively shallow and ofcorrespondingly-increased horizontal extent, as shown best in Fig. 2,the checker-work extending continuously from one side to the other ofthe chamber and the checker-work engaging the front wall of the chamberand extending rearward to a divisional wall 15, With extensions from thebottom of the chamber up vertically to the upper level of thechecker-work.

a series of oil 16 indicatestwoinlets for the oiLand atomizingfluids,these'being located'oneabove and Y one below the checker-work.,Oommunicating with the said inlets are the discharge-portsof Zcentrifugal air-pumps 17, and passing tov said pumps are steam-jet pipes18. :Passing laterally into'the passages 16'are pipes 19, which havecommunication with steam-pipes -20 an d oil-pipes 21. Said pipes 19terminate within the passages 16 in spray-rings 22l, (best shown in Fig.3,) and comprise tubularrings,s.with and steam discharge orificestherein. I

23 indicates a'gas-outle-t which passesfJaterally from the lower part ofthe chamber below the checker-work. 1

At its rear end the chamber 10 is provided with a stack 24, whichcommunicates with the lower part ofthe chamber 10 rearward of the Wall15 by means of a base brancli 25. Discharging into this base branch isasteam-jet pipe 26, which is located in an air-pipe 27, extending upwardand forward into the branch pipe, as shown. Bymeans of the steam-jetfrom the pipe 26 and the air-s mply 2'7 sufiicient current may becreated in the furnace to blow off or properly cleanse the sameat suchintervals as the conditions may require, during which operation themanhole-covers 11 may be removed or an outlet from the generator may beprovided in any other manner desired. The stack; 24.. is provided with adamper 28.

The manner of operating and using the apparatus is as follows: Themixture of oil and steam is sprayed through both burnerrings,accompanied by blasts of air from the'pumps 17. The combustible vaporthus formed is ignited and burns in both chambers of the generator, thedamper28 being open to allow a draft through the stack 24. When thechecker-work becomes sufficiently hot, the supply of air is cut off andthe flame at both lfurners is extinguished. Then the mixture of steamand oil is turned on through the upper ring 22 only, and the damper 28is closed. The vapor contacting with the hot checker-work istransformedinto a fixed gas, expands in the chambers of the generator,

and is withdrawn through the conduit 23. When the generator becomescold, the operation is repeated.

The exact manner of operating the apparatus when making gas is notessential. For instance, the mixture of steam and oil may he turned onthrough the lower ring 22 and the gas withdrawn from the upper part ofthe apparatus.

Lylavin g thus described my invention, I claim as new'and desire tosecure by Letters Patent 1. A gas-generator having exterior wallsforming a chamber, a series of piers erected on the bottom of thechamber extending horizontaily, a cliecker-work erected on the piers andextending horizontally throughoutthe major; portion of the length ofthechamber, means for introducing fuel and atomizing fluids into thechamber above and below the c'heckeravork and for withdrawing the resultant gases, the said checker-work being spaced from one end wall of thechamber, a divisional wall located in the chamber and extending from thespaced end of the checker-work downward to --the bottom of the chamber,a stack communicating with the lower part of the chamber at the side ofsaid divisional wall opposite the checker-work, and a blowoff means alsocommunicating with the chamber at the lower part of one end thereof atthe side of the divisional wall opposite the checker-work.

2. A gasgenerator comprising exterior walls foaming ahorizontally-elongated chamber, a series of piers erected on the bottomof the chamber and extending l'iorizontally therein, a checkenworkerected on the piers and extending horizontally .in the chamberthroughout the major portion of the length thereof, the generator havingcombustion and expansion spaces above and below the checkerwork, meansfor introducing fuel and an atomizing fluid above and below thechecker-work and for witlnlrawing the resultant gases, the saidchecker-wm-k being spaced from one end wall of the chamber, a divisionalwall located in the chamber and extending from the spaced end of thechecker-work downward to the bottom of the chamber, a stackcommunicating with the lower part of the chamber at the side of saiddivisional wall opposite the checker-work, and a blow-off-n'ueans alsocomnnujiicating with the chai'nber at the lower part of one end thereofat the side of the divisional wall opposite the checker-work.

3. A gas-generator comprising exterior walls forming a chamber, a seriesof piers erected on the bottom of the casing and extending horizontallytherein, a checker-work erected on the piers and also extendinghorizontally in the chamber, the checker-Work being spaced at one endfrom the end wall of the chamber, a divisional wall extending from saidspaced end of the checker-work downward to the bottom of the casing,means for introducing fuel and an atomizing fluid above and below thechecker-work, means for withdrawing the resultant gases, a stackcommunicating with the lower part of the casing at the end adjacent tothe divisional wall and at the side thereof opposite the checker-work,blowoff means communicating with the base of the stack, and a damper inthe stack above the blow-off means.

4:. A gas generator comprising exterior walls forming a chamber, anair-blower discharging thereinto, a ring located in the airblowerdischarge and having a plurality of discharge-openings, means forsupplying fuel and an atomizing liuid to said ring, and a meanscommunicating with the blower for discharging an elastic fluid underpressure into the blower.

5. A gas-generator comprising exterior walls forming a chamber, anair-blower discharging thereinto, means for delivering a fluid-jetlocated in the air-blower discharge,

means for supplying "fuel and an atomizingblast to said means fordelivering a fluid-jet, and a i'neans communicating with the blower fordischarging an elastic fluid under pressure into the blower.

6. A gas generator comprising exterior walls forming a chamber, anair-blower discharging thereinto, means for delivering a fluid-jetlocated in the air-blower discharge, and means for sumilying fuel and anatomiz ing fluid to said means for delivering a fluid jet.
